Introduction
In today's fast-paced digital landscape, email systems need to handle thousands of messages per second while maintaining reliability and security. After optimizing our email infrastructure, we achieved a 10x improvement in processing speed. Let me share our journey and the key strategies that made this possible.
The Challenge
Our email system faced several critical challenges:
- Processing 100,000+ emails daily
- Maintaining 99.9% uptime
- Ensuring real-time delivery
- Managing complex email templates
- Handling high concurrency
Our Solution Architecture
1. Asynchronous Processing Pipeline
import asyncio
from aiohttp import ClientSession
from typing import List, Dict
class EmailProcessingPipeline:
def __init__(self, max_concurrent: int = 100):
self.semaphore = asyncio.Semaphore(max_concurrent)
self.session = ClientSession()
async def process_batch(self, emails: List[Dict]):
tasks = []
for email in emails:
task = asyncio.create_task(
self._process_single_email(email)
)
tasks.append(task)
return await asyncio.gather(*tasks)
async def _process_single_email(self, email: Dict):
async with self.semaphore:
# Process email with rate limiting
return await self._send_email(email)
2. Smart Queue Management
from redis import Redis
from datetime import datetime
class EmailQueueManager:
def __init__(self):
self.redis = Redis(host='localhost', port=6379)
self.priority_queues = {
'high': 'email:queue:high',
'normal': 'email:queue:normal',
'low': 'email:queue:low'
}
async def enqueue_email(self, email: Dict, priority: str = 'normal'):
queue_key = self.priority_queues[priority]
await self.redis.lpush(queue_key, json.dumps(email))
3. Template Optimization
class EmailTemplateEngine:
def __init__(self):
self.template_cache = {}
self.compiled_templates = {}
def compile_template(self, template_id: str, content: str):
# Pre-compile templates for faster rendering
self.compiled_templates[template_id] = self._compile(content)
def render(self, template_id: str, data: Dict) -> str:
return self.compiled_templates[template_id].render(data)
Performance Optimization Techniques
1. Connection Pooling
class ConnectionManager:
def __init__(self, max_connections: int = 50):
self.pool = aiohttp.TCPConnector(
limit=max_connections,
ttl_dns_cache=300
)
self.session = aiohttp.ClientSession(connector=self.pool)
2. Caching Strategy
class EmailCache:
def __init__(self):
self.redis = Redis(host='localhost', port=6379)
self.cache_ttl = 3600 # 1 hour
async def get_cached_email(self, email_id: str) -> Optional[Dict]:
cached = await self.redis.get(f"email:{email_id}")
return json.loads(cached) if cached else None
Real-World Implementation
Case Study: Omypost Integration
